Breeding problem

[Tony_JB]

Hi,
I have 3 pairs,one of them proved. My problem is that any time when they spawn after 2 days noting stay on cone.
Parameters of water are:
PH 6.3-6.5
GH 2
KH 7
Water is soft in my area and TDS should by fine.
Do is possible KH to be my problem?
And light is needed when they spawn or just leather?

Hello Tony, from my knowledge light is only needed for the adults to actually breed, the adults to see the area where they bred, and for the fry to see the parents. You can do this with a simple night-light.

The eggs going away AND IF they are the only fish in the aquarium. They are likely still trying to get into the swing of breeding and accidentally eating the eggs.

On second day eggs are getting less,and between day 2-3 are finishing. Once when they put egg's on cone everything is fine. When some egg is white they clean and eat the egg. It is proved pair once I have already baby's from them.
All off my pairs (3) are in separate aquarium 120 liters, with sponge filter and heater only.
Temperature is 29-30 C and oder parameters I already write in beginning.

IMO the high kH is for sure your problem. You can lower it with RO, peat, or Rooibios tea which is what I use on my breeders. https://www.amazon.com/Davidsons-Tea...D4994YG11&th=1

Yesterday I put peat from Sera. I will wait to see if there is different results this time.
